Snow Guard placement will vary from region to region and will be influenced by roof pitch, as well as the length of runs and seam spacing. Recommendations can be found in Sheet Metal and Air Conditioning Contractor's National Association Architectural Sheet Metal Manual and other industry standards. Best practice with any installation is to develop a layout aimed at retaining the snow in place rather than trying to stop it at the eaves after it has begun to slide. This principal is twice as important where adhesive mounted devices are to be relied upon.
Seam Mounted Snow Guards are installed with hex bit sockets and a standard 3/8" drive ratchet, making installation quick, easy and consistent. Torque will vary with thickness and metal type Installation is so easy that they can be readily installed by maintenance personnel, and can be retrofit on existing structures when-ever and where-ever sliding snow becomes a problem.
Surface Mounted Snow Guards are provided with four starter dimples through which self tapping screws may be driven. It is recommended that holes be pre-drilled before inserting self tapping screws. Fastener selection should be governed by substrate and anticipated loads, but stainless steel or corrosion resistant fasteners with neoprene washers should be insisted upon. Adhesive or sealant should be applied so as to completely cover the underside of the device before it is positioned. Sufficient compression must be created to squeeze adhesive/sealant out around its entire perimeter and a bead of the same material must be applied to create a waterproof joint free of gaps or air pockets.
Surface Mounted eGutter™ Snow Guards can be installed using adhesive alone or in combination with self-tapping screws or other suitable fasteners.
